How the tables turn

All of us were playing cards in Nicoles' room it was fun until the lights of the train flickered off and the train lurched to a stop. "Seriously what keeps hape-" a gunshot went off everyone screamed, "Oh my god, what just happened!?" Evaline said in a panic. they all heard a clattering on the ground outside of Nicoles' room. The lights of the train flickered back on and lurched back onto the tracks. "Holy, crap!" Christy said. Nicole was lying dead across from Dill and next to Evaline there was a gunshot wound in the middle of her forehead. "Nicole!? Oh my god, Nicole how could they do this to you!?" Evaline said as she started to cry. "Well, we all know who is not the murderer," I said. "Wait did we dust for fingerprints?" Christy asked. "No, I would I just left my fingerprint kit at home," I said. "So who do yall think it is?" Aria asked. "It's between Jacob, Dill, and Nathan," I said. Evaline Pointed to Dill still in tears. Christy believed it was Nathan. Aria thought it was Dill. Jacob, Dill, and Nathan thought it was Evaline. "Why do yall think it's Evaline?" Aria asked. "Who knows she might've killed Nicole to make it seem she didn't do it," Nathan said. "You think those tears are fake!?" I said. "Yeah, she probably staged this entire thing," Dill said. "Evaline would NEVER, Do anything like this to her best friend," Christy said. "How do you know that?" Jacob asked. "Before Aria moved in Evaline lived with us but then Evaline moved to her own house and Aria took her spot," I said.
